National Accounts in the Anthropocene : Hueting’s Environmental Functions and Environmentally Sustainable National Income: Translation and Relevance for Ecosystem Services

The UN System of National Accounts (SNA) calculates standard national income (NI) under the condition that owned capital is maintained. Roefie Hueting defined in 1969 environmental functions (state, stock) as the possible uses by humans of the environment. Their actual use (flow) nowadays are also called ecosystem services. Hueting defined in 1986 environmentally sustainable national income (eSNI) (flow) under the condition that the vital environmental functions are maintained for future generations. Then eDelta = NI – eSNI gives the national distance to environmental sustainability. Thus eDelta measures the level of ecosystem services concerning the part that infringes upon environmental sustainability, or the abusive part in the ecosystem services that are provided. This communication aspires at a translation of the terminologies by economist Hueting and ecologists in the research of ecosystem services
